Tina Peters, the former clerk of Mesa County, Colo., was convicted on Monday of tampering with voting machines under her control in a failed attempt to prove that they had been used to rig the 2020 election against former President Donald J. Trump.
After nearly five hours of deliberations, a jury in Grand Junction found Ms. Peters guilty of seven criminal charges connected to her efforts to breach a machine manufactured by Dominion Voting Systems. The jury determined that Ms. Peters had helped an outsider gain unauthorized access to the machine in May 2021 and obtain information that was later made public at a conspiratorial event held to undermine trust in Mr. Trump’s defeat to Joseph R. Biden Jr.
